The SM15T33AY is a unidirectional Transient Voltage Suppression (TVS) diode manufactured by STMicroelectronics. Designed for automotive applications, it provides protection against voltage transients by clamping overvoltage events. The device has a reverse standoff voltage of 28.2V and a maximum clamping voltage of 59V at a peak pulse current of 169A (8/20µs waveform).
With a peak pulse power rating of 1500W (1.5kW), the SM15T33AY can handle significant surge energy. The device is unidirectional, making it suitable for DC line protection. It is not designed for power line protection.
The SM15T33AY is mounted using surface mount technology and is packaged in a DO-214AB (SMC) case. The operating temperature range is -40°C to 150°C (junction temperature). The device is rated RoHS3 compliant and REACH unaffected, with a Moisture Sensitivity Level of 1 (unlimited).
The SM15T33AY is suitable for use in automotive electronics, industrial systems, and other applications requiring robust transient voltage protection. Its compact SMC package allows for space-efficient PCB layouts.
